Abstract

Abstract A pneumatically driven motor assembly causing rotation of the drive shaft, the drive shaft rotating a drive gear which rotates an idler gear assembly including a pair of simultaneously driven, spaced-apart, idler gears, a wrench gear being driven by the pair of idler gears with the wrench gear having a radial opening therein to be able to cooperate with a polygonal-shaped fastening device, a positioning pawl secured to the drive shaft, a stop being longitudinally movable along the drive shaft upon actuation of the trigger, upon release of the trigger the stop contacts the positioning pawl thereby locating the wrench gear in a particular predetermined positioned.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 241 words
An apparatus comprising: a pneumatically driven portable tool including a grip and a barrel, a driving motor assembly located within said barrel, said grip including a valve to regulate the flow of driving fluid to said driving motor assembly, said valve being actuatable by a trigger, said trigger being movable between a first position and a second position; a drive shaft being rotatable by said driving motor assembly, a drive gear being connected to said drive shaft, said drive gear being located within a gear housing; an idler gear assembly including at least a first and second idler gear, said idler gear assembly being located within said gear housing, said first and second idler gears being rotatable by said drive gear; a wrench gear being simultaneously rotatably driven by said first and second idler gears, said wrench gear being located within said gear housing, said wrench gear having a radial opening therein to cooperate with a polygonal-shaped fastening device, an aperture within said gear housing, said radial opening being alignable with said aperture to permit entry and removal of the fastening device; and a positioning pawl secured to said drive shaft, a stop movable between a first and second position, said stop being able to contact said positioning pawl with said stop in said first position, with said stop in contact with said positioning pawl said radial opening of said wrench gear in alignment with said aperture of said gear housing.
Claim 2
Independent Claim 241 words
An apparatus comprising: a pneumatically driven portable tool including a grip and a barrel, a driving motor assembly located within said barrel, said grip including a valve to regulate the flow of driving fluid to said driving motor assembly, said valve being actuatable by a trigger, said trigger being movable between a first position and a second position; a drive shaft being rotatable by said driving motor assembly, a drive gear being connected to said drive shaft, said drive gear being located within a gear housing; an idler gear assembly including at least a first and second idler gear, said idler gear assembly being located within said gear housing, said first and second idler gears being rotatable by said drive gear; a wrench gear being simultaneously rotatably driven by said first and second idler gears, said wrench gear being located within said gear housing, said wrench gear having a radial opening therein to cooperate with a polygonal-shaped fastening device, an aperture within said gear housing, said radial opening being alignable with said aperture to permit entry and removal of the fastening device; and a positioning pawl secured to said drive shaft, a stop movable between a first and second position, said stop being able to contact said positioning pawl with said stop in said first position, with said stop in contact with said positioning pawl said radial opening of said wrench gear in alignment with said aperture of said gear housing.
Claim 3
Dependent Claim 23 words
An apparatus as defined in claim 1 wherein: said stop being movable between said first and second positions by actuation of said trigger.
Claim 4
Dependent Claim 24 words
An apparatus as defined in claim 2 wherein: a bar connecting said stop to said trigger, said bar being movably retained within said barrel.
Claim 5
Dependent Claim 51 words
An apparatus as defined in claim 3 wherein: said positioning pawl is substantially pointed at one end, whereby upon movement of said stop from said second position to said first position and direct contact results between said pointed end and said stop said positioning pawl will continue to rotate another revolution.
Claim 6
Independent Claim 99 words
An apparatus comprising: a rotatable drive shaft, said drive shaft being secured to a drive gear, said drive gear being connected to an idler gear assembly, said idler gear assembly effecting rotation of a wrench gear, said wrench gear having a radial opening therein to cooperate with a polygonal-shaped fastening device; a wrench gear housing containing said wrench gear, an aperture within said wrench gear housing, said radial opening being alignable with said aperture To permit entry and removal of the fastening device; means secured to said drive shaft for positioning said radial opening in alignment with said aperture.
Claim 7
Independent Claim 99 words
An apparatus comprising: a rotatable drive shaft, said drive shaft being secured to a drive gear, said drive gear being connected to an idler gear assembly, said idler gear assembly effecting rotation of a wrench gear, said wrench gear having a radial opening therein to cooperate with a polygonal-shaped fastening device; a wrench gear housing containing said wrench gear, an aperture within said wrench gear housing, said radial opening being alignable with said aperture To permit entry and removal of the fastening device; means secured to said drive shaft for positioning said radial opening in alignment with said aperture.
Claim 8
Dependent Claim 54 words
An apparatus as defined in claim 5 wherein: said means includes a positioning pawl, said pawl secured to said drive shaft, said means further includes a stop to be contactable with said pawl, said stop being movable between a first position in contact with said pawl to a second position disassociated with said pawl.
Claim 9
Dependent Claim 51 words
An apparatus as defined in claim 6 wherein: said positioning pawl is substantially pointed at one end, whereby upon movement of said stop from said second position to said first position and direct contact results between said pointed end and said stop said positioning pawl will continue to rotate another revolution.
